Project Ideas anything digital? something thats interesting enough? What have people done? w Lots of variations on processors n Usually 16-bit n Usually custom RF, perhaps custom ALU n Usually distinctive I/O l R/W
n Usually 16-bit n Usually custom RF, perhaps custom ALU n Usually distinctive I/O l R/W pins, memory mapped I/O, UART, VGA, LCD, PS/2,
etc.
n CORDIC processor n Controller for a light-based toy n Stack-based processor n Communicating multiprocessor node

n 64k addresses n Each address is a 16-bit word n So, 128k bytes of data, but organized as words l Clearly this needs to go off chip! n You probably need to reserve some I/O addresses l Up to you, but I recommend using the some top address bits l Upper 16k words (32kbytes) as I/O space? n You probably need to reserve some part of the address
l Up to you, but I recommend low addresses
